crwdns2931653:03crwdne2931653:0 Remove the top cover
• There is no need to remove its rubber feet since it is held together by only one screw.
• Wiggle the grey part of the top to remove it by pulling it towards you(away from the scroll wheel).
• Do not pull the grey cover towards the top and do not pull the part near the keys.
• Reasoning by Jacob Hickey "because in the internal top part of the mouse where the buttons/scroll wheel is, there’s hinges-like “tooth” that’ll snap if you do pull on it. It’s like opening a jewelry box that has a hinge on one end of the box… if that makes sense…"
• The image is what your mouse should look like in the end.
